Definitely! If you start a game (e.g. pulling cord under door) Pandy gets right into it, jumping around like she was 2, instead of (also) 16! And she still plays hockey with little things as long as I keep the two male 'kids' out of her way.
Before my dear Fred went to the Bridge at the age of 18, he played for most of his life. It was only after he became ill that he did not play, but he would for a few minutes on a good day. I still have his favorite toy, and the others love it. It is a wand with a suede tassel on it.
